# Sample toolchain file for building for Windows from an Arch Linux system.
#
# Typical usage:
# 1) install cross compiler: `sudo pacman -S mingw32-gcc`
# 2) cp cmake/Toolchain-Arch-mingw32.cmake.sample ~/Toolchain-Arch-mingw32.cmake
# 3) tweak toolchain values as needed
# 4) cd build
# 5) cmake -DCMAKE_TOOLCHAIN_FILE=~/Toolchain-Arch-mingw32.cmake ..
# name of the target OS on which the built artifacts will run
# and the toolchain prefix
set(CMAKE_SYSTEM_NAME Windows)
set(TOOLCHAIN_PREFIX i486-mingw32)
# cross compilers to use for C and C++
set(CMAKE_C_COMPILER ${TOOLCHAIN_PREFIX}-gcc)
set(CMAKE_CXX_COMPILER ${TOOLCHAIN_PREFIX}-g++)
set(CMAKE_RC_COMPILER ${TOOLCHAIN_PREFIX}-windres)
# target environment on the build host system
# set 1st to dir with the cross compiler's C/C++ headers/libs
# set 2nd to dir containing personal cross development headers/libs
set(CMAKE_FIND_ROOT_PATH /usr/${TOOLCHAIN_PREFIX} ~/crossdev/w32)
